This application is a division of my copending application, Serial No. 8,989, filed March 2, 1935,

j for Liquid treating vessel and support therefor which application became Patent 2,079,333, dated May 4, 1937. r e

An object of, the invention-is to provide a sim- 'ple, rigid, 'dependableand economical support of e the above type. t

Another object is to provide a support which may be attached to the vessel at the factory and which facilitates the erection oi the vesselin thefield.

.Various other objectsand advantages will be apparent as the nature of thelinvention' is more fully disclosed.

2 The invention is capable-oi various uses and -will be understood from the followingdescrip tion, taken in connection with the accompany ling drawing in which one embodiment thereof is set forth. In the drawing.

' Fig. 1 is a vertical section of a portion of. a

Referring to the drawing more in detail, theinvention is. shownapplied to a vessel Ill. which may comprise a flashchamber or the like in anoil cracking plant. Such vessels' are. of large dimensions and comparatively heavy. For supporting the vessel Hi there are provided a pluralityof legs ii, preferably four in number.

to each. of which comprises a tubular member l2,'

suchas a steel rod, to which a pair of cross plates l3 and M are secured, as by welding. 'lfihe cross plate 83 may be provided with an aperture 15 through 'whichn'the tubular member llextends.

. 5mm cross plate 14 is preferably butt-welded to 55 extend between the cross plates l3 and It irom beendisclosed. for purposes of illustration, it is suitable for the various heavytowers and vessels --the tubular member i2 to the outer surface oi! the vessel Ill to enclose the assembly and to intubular member I2 and to the wall of the .vessel I ID are preferably butt-welded so as to form a rigid mounting for the legs. The various plates form, ineffect, an open box or truss, the edges of.which may readily be secured to the vessel and which is adapted to support me weight of the vessel rwlthout distortion. The". vessel may be constructed at the factory with the-legs II attached thereto, so that the amount 01' construe-- tion work in the field is reduced to a minimum.

A base 20', of any suitable. material such as concrete, may be formed with recesses adapted" to receivethe legs H. The tubular members l2 'enter said recesses and are secured therein by concrete. The tubular members I2 are also pro-v vided with an outer coating 2! of concrete, which strengthens the assembly and protects the members from injury. This coating 2| may be ap- 1 The shell 22may remain in position permanently to protect the concretefrom damage. I I

Although aspecific form of supporting leg has obv ous that yarious changes and modifications me be made-therein by a person skilled in the .art without departing from the scope oi the invention. The supporting legs are particularly used in an oil cracising plant. It is to be understoodfhowever, that the use of these supporting legs isnot limited .to such apparatus. -Thescopeoi the invention is only to.be limited in accordance with the following claim, when interpreted in view of the prior art. r

: What is claimed is; g A support for a heavy metal vessel comprising. a plurality of supporting legs and a butt-welded truss, securing each leg-to said vessel, each or said trusses comprising a'horizontal plate buttwelded to the top 01 a leg and having an edge engaging and butt-WeIde d. to'the surface of said vessel; a second horizontal plate having an opening through which saidleg extends, said second plate being horizontally spaced below said first plate and likewise being butt-welded both to said leg and to said vessel, side plates closing the area .between said horizontal plates and said vessel,

said side platesbeing butt-welded to said vessel 66 and said first plates a pair of triangular plates above the upper transverse plates and in ap-i.

proximately the planes of said side plates, said triangular plates being butt-welded to the upper transverse plate and to said vessel and an inclined plate butt-welded to said triangular plates and to said vessel to close the area between said triangular plates,tsaid plates forming, in effect, an open. box-like truss which is resistant to deformation and forms a rigid support for said vessel.
